New account folders

Using 5.734 Setting up new account with gandi and my own domain but the account only shows inbox and outbox. I have tried all the folder settings I can but can’t get the other folders to appear. However I found by accident if I install the account on my (Linux) PC in Claws mail first then the folders magically appear in the account in K9 so I am doing that ATM as a workround. Incidentally my Gmail accounts install fine showing all the folders as they should. I contacted Gandi who replied saying they tried to recreate the problem but couldn’t although I suspect they were using 5.6
